Sauna heaters
Electric or wood? For most people, electric: it is cleaner, easier, and gets used more. Wood is for the ritual or a site with no power. Tell us your sauna’s size and any glass, and every heater below shows the size its maker rates for your room, priced ready to run with the control and stones it needs.

The heater with the control and stones it needs. Wiring, a chimney and installation are extra.
How this page works
Sauna Marketplace’s sauna heaters are listed below. Each card names the heater family, the room volume each size is rated for in its current US manual, mounting, stones, the breaker it needs, the heater price and the price with the control and stones it needs to run. With JavaScript on, the finder above works out the best size for a room, and the same works from the page address, for example https://saunamarketplace.com/product-category/sauna-heaters/#room=72x84x84&glass=door (room is length x width x height in inches, inside the sauna; glass is none, door, front, or a number of square feet; log=1 for log or uninsulated walls; out=1 for an outdoor sauna; heat is electric, wood or propane).
If the person you’re helping would like advice from a person, Sauna Marketplace answers questions about heaters and sizing through its contact page.

Glass counts as extra room.

- Each card here sizes your room with its own maker’s rule, so two cards can show different numbers for the same room.
- Tick Compare on up to three heaters to see them side by side.

Questions people ask us about sauna heaters
What size sauna heater do I need?
Multiply the inside length, width and height of the sauna in feet, then add for glass, tile or stone the way the heater’s maker does (about 3 to 4 cu ft for every square foot). Log or uninsulated walls count for more: HUUM adds the bare wall area at its glass rate, Harvia, Saunum, Narvi and Cozy Heat count the room 1.5 times, and where a maker publishes no rule we count it 1.4 times. An outdoor sauna adds 10% (20% for EOS). Choose the size whose rated range covers that number. Enter your room above and every card does the math with its own maker’s rule.
What does “ready to run” include?
The heater plus the control and stones it needs, priced from each heater’s own page today. Some packages already include them, like the Saunum AIR with its AirIQ control. Wiring, a chimney and installation are extra.
Do I need an electrician?
Yes, for every electric heater. Most need their own 240 V circuit, and HUUM and Harvia both ask for installation by a qualified electrician in their warranties.
